In attempt to make a moving mouth, the lower jaw was cut from the upper part of the mask and crudely hinged with a set of corner-brackets from a local hardware store. In the pic, the jaw has already been fabric-coated, and is in process of receiving dental work. Gums and tongue are from latex pipe-sealant putty. The teeth come from molded plastic bear & eagle claws that I got from the jewelry-making section of Hobby Lobby and cut down to fit my needs.
